Application filed November 30,1914. Serial 'No.-874;587.

To aZZ whom it may mm e Be it known that I, NAOMI Ev Niorronson, a citizen of the United States, residing at Los Angeles, in the county of 'Los A'ngeles,

State of California, have inventeenew and I useful Improvements in Twine Cut'tersfof which't'he following is a specification.

This invention relates to atwine'c'utter. It is the object of this invention toprovide a device for cutting twine and which is'particularly adapted for useby package wrappers insevering the twine after tying same on the package, and which is used in lieu of shears or like implements. 1

Another object is to provide a tool for cutting twine having a demouritable cutting blade formed with a V-shaped cutting edge, in which the blade can be readily removed and replaced when itis desired to renew or resharpen same. A further object is to provide a holder for a twine-cutting blade which can be readily grasped in the hand, together with the cord or twine 'to be cut and the latter severed on a drawingor pulling movement of the tool in opposition to the securedend of the cord. I

Another object isto provide a'twine cutter comprising a demountablecutting blade and holder therefor which is durable and,

which can be economically manufactured and sold at small cost.

The invention is illustrated in the accompanving drawings, in which:

Figure l is a perspective view illustrating the application of the invention. Fig. 2 is a view of the device in side elevation, with parts broken away. Fig. 3 is a view in end elevation, as seen in the direction indicated by the arrow 3 in Fig. 2. Fig. 4 is an enlarged end view of the device, as seen in the direction indicated by the arrow 4 in Fig. 2, with parts broken away. Fig. 5 is a perspective view of the demountable cutting blade. Fig 6 is a view in perspective illus trating a modified form of the invention, showing it as adapted to be readily mounted on a counter or other support.

More specifically, 10 indicates the body portion of the device which, in the form shown in Figs. 1 to 4 inclusive, comprises a blade holder adapted to be held in the hand and grasped between the thumb and first and second fingers. The body member or blade holder 10 is preferably formed of cast metal or other material and consists of a ring ,portion 11, having an. open portion substantially of piriform formation to receive the second or middlefinger' and which is of suflicient size that the finger may extend diagonally therethrough to engage the ring 11 between the second and third oints ofthe finger, asparticularly shown in Fig. 1. .The'outer face of the ring 11 converges on one side thereof'into an extended portion wli ichportion is formed with a substantiallyflat face 13, to form a seat for the thumb and against which a cord or twine 14 to be cut is held by the thumb, as shown in Fig. '1.

vFormed on the'extension 12 opposite the flatface 13, isan outwardly extending ear 1'5, havinga concave face forming aseat l6,fortheend of the first finger. The extension .12 is formed with a projectingportion '17, extending =rearwardly of the ring 11, that is, on the side of the latter disposed towardtheipalmof the hand when the body member 10 is grasped in the fingers. Formed on this projectingportion1'7 is an outwardly extending portion 18, arranged 'atright angles to the face 13, on which is formed a rigid member 19.

Thejaw member 19 extends substantially parallel with the face 14 and is spaced therefrom to form an open" ended twine receiving slot 20, the walls of which converge inwardly and are formed by the inner face of the aw member 19 and the face 13 at the outer edge of the extension 12; the outer edge of the extension 12 forming a rigid jaw member 21, cooperating with the jaw member 19 to form the slot 20.

Formed in the extension 12, projection 18 and the jaw member 19, is an open ended slot 22, disposed at right angles to the slot 20 and terminating approximately midway of the length of the jaw members 19 and 21 to form shoulders 23 and 24. This slot 22 is designed to receive a demountable cutting blade 24, having a V-shaped notch on one end thereof, which notch is beveled to form a convergent or V-shaped cutting edge. The blade 24, when inserted in the slot 22, extends across the slot 20, with the end of the blade carrying the V-shaped cutting edge 25 abutting against the shoulders 23 and 24, with the V-shaped cutting edge 25 disposed across the twine receiving slot 20 and opening to the slot 20 in such manner that when a cord 14 is introduced into the latter, it will be engaged by the cutting edge 25, as shown in Fig. 4. The upper wall of the blade receiving slot 22 thus forms a tongue 26, adapted to project over the cutting blade 24. This tongue 26 is formed with an aperture 27 adjacent its outer end, adapted to register with a corresponding aperture 28 formed in the cutting blade 24. The projection 18 is formed with a threaded bore 29, arranged opposite the aperture '27, which is adapted to receive the threaded stud of a screw 30, which screw is adapted to be inserted through-the apertures 27 and 28-and screwed into the bore 29 to clamp the blade 24 between the tongue 26 and the bottom wall of the blade receiving slot 22. The screw 3O thus serves to removably hold the cutting" blade 24 in position on the blade holding member 10. The blade holder 10 is fitted with an eye 31, adapted to receive a looped cord or ribbon 32, by means of which the 7 suitable 1 device may be suspended from any support.

In the application and operation of the invention as previously described, the device is I grasped in the hand with the second finger passing diagonally through the ring 11 and engaged between the second. and third joints (topics of this patent may be obtained for thumb. A pull being enertedon the device in the direction indicated by'the arrow in Fig. 1, the cutting edge 25 of the blade will engage the cord 14 and sever same.

In the modified form of the invention illustrated in Fig. 6, it is shown as adapted to be permanently mounted on a counter, table or the like. In this form of the invention the blade supporting member 10 is formed with a flange adapted to sit on a suitable supporting surface 36 and secured to the latter by means of a screw 37 or any other suitable fastening means. The cord 14 to be severed is introduced into the open ended slot 20 and drawn, into cutting engagement with the V-shaped cuttingedge 25 of the blade 24.

I/Vhat I claim is: l

A twine cutter, comprising a loop member 'of elongate form provided with an oil-set ear on one side for engagement by a finger and an offset jaw member oppositely disposed to said ear at one end thereof, said body member comprising a pair of spaced jaws having registering grooves formed therein lying in a plane substantially parallel to the plane of the jaws and open at the closed end of the jaw member, a cutting plate disposed in said grooves, and a set screw mounted on the member for detachably securing the knife in place. 1

In witness that I claim the foregoing I have hereunto subscribed name this 9th day of November, 1914.
